OF DETROIT,

THE ELECTROGRAPH PRINTING PRESS.

Application filed March 25, 1926.

My invention relates to printing presses and an object of my improvement Vide an impr ;-ved way 0 ating an inking ribbon through which the impress of the type is is to prof mounting and operto be made.

My improvement has been designed to be used in the apparatus described and claimed in a co-pending application, filed by James Beatty, and having 65,534, in connection it IS herein shown. In the drawings:

the Serial Number ith which apparatus Figure l, is a side elevation of a printing press with an apparatus embodying my invention thereon.

Figure 2, is a view of the frisket. friskct ribbon operating appa Figure 3, is a section Figure 2, looking in arrows.

to an enlarged scale -bearing frame, and ratus in said frame. on the line ll11ll, the direction of the Figure 4, is a detail elevation of the upper roll-actuating right of Figure 2.

Figure 5, is

apparatus looking from the a section on the line V-V,

Figure 6, is a plan view of the actuating apparatus shown at the upper corner of Figure and to.

right hand parts adjacent there- Figure 7, is an elevation, to an enlarged scale, of the lower roll thereof.

a is the platen. Z), the

and actuating parts bed and c the frisketbearing frame of a printing press.

small type-form for printing the e upon the platen a. b presenting a platen and c, c", are double openings 0 and 0" the plate a prints upon a frisket sheet 0 over criloed more fully in referred to. f, is a message.

The frame 0 is made up of uprights u u, a horizontal bar 71 rectangular in crosssection extending between the upper ends of said uprights and a similar bar 71, extending between the lower ends of the same.

bar it is provided with The properly spaced vertically extending screwthreaded holes ha,

roller. j, is a pawl pivoted to an upright and adapted to engage the teeth of the ratchet wheel to prevent a reverse ment of the same. m, horizontal oscillating lever pivoted at its center upon the arbor of the drum j and extended both ways therefrom. Upon the end toward the bed I) said lever carries a. head upon which is pivoted an actuating pawl j, which engages the teeth of the wheel j mj is a pin extending laterally from the lever m. j, is a lever pivoted at my to an end of the lever 02. and having its angular movement in one direction limited by the pin onj. 922,5 is a spring acting upon the lever j to hold it yieldingly in contact with the pin 7257'. The lower end of the lever j is made concave at 7' to adapt it to be engaged by the platen to oscillate said lever and thereby the lever 72), as indicated in broken lines in Figure 4.

j, is a milled head adapted to rotate a short shaft bearing in the head j. j". is a cam upon the opposite end of said shaft adapted to be rotated hv he milled head j and when so rotated to turn the pawl about its pivot and disengage it from the teeth of the wheel j" and hold it disengaged. j. is a rod adapted to reciprocate through an aperture in the standard and having a cainined edge at one end adapted to engage the pawl j and hold it out of engagement with the teeth of the wheel it the lower end of the frame 0. there are standards ii, 1, corresponding to the standards 7'. j, and a. roller, and actuating mechanism therefor, entirely similar to that above described, except that the standards It, is, are secured to a flat bar it which is provided with an attaching lug n by which it is secured to the cross bar it of said frame by a bolt nh passing through slots a, at

move- 15 an approximately any position desired, and the oscillating lever is provided with an integral extension 767, instead of the pivoted lever operated by a cord or wire 9 secured to the outer end of said extension at one end and to a part of the press at the other end so that said wire shall be drawn upon at each operation of the press.

The parts at the lower end of the frame 0 are indicated by the letter 7.: with the figure indicating a part corresponding to that let tered j with the same figure at the top of the frame.

The lever m and the corresponding lever km are returned to their normal positions by springs y and 1 after being actuated by the moving press.

is an inking ribbon that is wound around the rollers j and k passes through slots 0" and 0 in one sheet of the double frisket and in front of the opening (and 0 The operation of the above described de vice is as follows:

The form and position of the address plate is adapted to the work to be done and the openings in the frisket sheet selected accordingly. The rollers art then secured in their proper positions on the cross bars of the frame (J with the ribbon secured to said rollers and passing in front of the opening in the frisket sheet.

If the ribbon is wound on the low-er roller 7., the pawl In is disengaged from the teeth of the wheel 7.? by turning the cam 7r" by means of the milled head In, and the pawl 70 by pressing the rod. is inward is forced out of engagement with the teeth of said wheel and held.

The. press is now operated, the edge of the platen a engaging the end j of the. lever arni j, and oscillating the lever on, thus moving the ratchet. wheel j and roller a short distance at each stroke.

When the ribbon has been wound upon the roller j", the pawls and are thrown out of engagement as above described for in and k and the last named pawls are caused to engage the teeth of the ratchet wheel 7.5.

Each time the press is operated the lover 1cm is oscillated by drawing upon the wire or cord Q and the ribbon is rewound upon the roller k What I claim is:

1. In an apparatus of the kind described. the combination of a frisket frame, a frisket thereon, the frisket frame having upper and lower cross bars, horizontal rollers adapted to be secured at various positions intermediate the ends of said cross bars, a vertically extending ribbon passing around said rollers and means for actuating said rollers to more the ribbon by the operation of the apparatus.

2. In an apparatus of the kind described, the combination of a frisket frame having upper and lower cross bars, horizontal rollers on said cross bars, a vertically extending ribbon upon said rollers and means for actuating said rollers, and a frisket sheet on said frame said ribbon passing through slots in said frisket sheet.

In an apparatus of the kind described, the combination of a frisket frame, a frisket thereon, a platen, a horizontal roller and means for actuating the same on said frame, said actuating means being adapted to be actuated by contact with said platen and a vertically extending ribbon passing around said roller.

4:. In an apparatus of the kind described, the combination of a frisket frame, a frisket thereon, a platen, a horizontal roller on said frame, a jointed lever pivoted directly on said frame and adapted to be actuated by contact with the platen and to actuate said roller and a vertically extending ribbon assing around said roller.

5. In an apparatus of the kind described, the combination of a l'rislcet fran'ie, a frisltet thereon, the trislcet frame having upper and lower cross bars, horizontal rollers adapted to be secured at various positions intcrn'iediate the ends of said cross bars, a vertically extendingribbon passing around said rollers and means for actuating said rollers to move the ribbon by the operation of the apparatus, and a filSliQt sheet having an opening a therethrough for the purpose described.

In testimony whereof I sign this specification.
